Preparation of cobalt thiocyanate trihydrate
A solution of 56 g of cobalt sulfate heptahydrate in 300 ml of water is heated to boiling and 65 g of lead thiocyanate is stirred in. When the lead sulfate is well settled, the mixture is cooled and filtered. The residue is washed with two 25 ml portions of cold water; the washings are added to the main filtrate which is then evaporated to dryness on the steam bath. The product is finally dehydrated at 105-120° C for 2-3 hours. The yield of crude cobalt thiocyanate trihydrate is 32 g. Cobalt thiocyanate trihydrate may be purified by dissolving it in ethyl acetate, filtering it, and then evaporating the solvent.
